icd9MajMinToCode

Deprecated. Single logical value which determines whether the
ICD-9 code provided is in short (<code>TRUE</code>) or decimal (<code>FALSE</code>)
form. Where reasonable, this is guessed from the input data. Use
<code>short_code</code> instead.

isShort

character vector of 'major' part of ICD-9 codes, i.e. that part
which falls before the decimal point, in decimal notation. (In five digit
notation, the 'major' part is be the first three characters (with leading
zeroes), and includes V or E prefix.

major

character vector of 'minor' part of ICD-9 codes, i.e. that part
which falls after the decimal point, in decimal notation. (In 'short' five
digit notation, the 'major' part is the first three characters including
leading zeroes which may be inferred; the last two characters represent the
'minor' part.)

Calculate comorbidities, medical risk scores, and
work very quickly and precisely with ICD-9 and ICD-10 codes. This
package enables a work flow from raw tables of ICD codes in hospital
databases to comorbidities. ICD-9 and ICD-10 comorbidity mappings from
Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ included.
Common ambiguities and code formats are handled. Comorbidity
computation includes Hierarchical Condition Codes, and an
implementation of AHRQ Clinical Classifications. Risk
scores include those of Charlson and van Walraven.  US Clinical
Modification, Word Health Organization, Belgian and French ICD-10
codes are supported, most of which are downloaded on demand.
